Embodiment Construction
[0024] Examples see figure 1 As shown, a village and town rainwater utilization system includes a pond and a rainwater drainage ditch connected to the pond. The courtyards of the households are adjacent to each other. There is a road surface 2 in the courtyard around the village house 1 in the courtyard of the households. There is a planting land 3 in the courtyard wall 8 of the courtyard of the households in the village and town. The planting land 3 is 1-5cm lower than the road surface 2 in the surrounding courtyard. The root of the wall 8 is provided with a drainage outlet 4 for discharging rainwater. The bottom surface of the drainage outlet 4 is flat or slightly higher than the surface of the plantation land 3, but not higher than the road surface 2 in the courtyard. The rainwater drainage ditch 5 is adjacent to the drainage outlet 4 One edge of the rainwater drainage ditch 5 is lower than the surface of the village road 6, and the other side edge of the rainwater drainage...

The invention discloses a system and method for utilizing rainwater in villages and towns. The system comprises a pool and drainage ditches arranged at two sides of a hardened road surface, wherein resident courtyards are arranged at two sides of the hardened road surface along the drainage ditches, the hardened ground and a planting surface are arranged between houses and a courtyard wall in the resident courtyards, the hardened ground is adjacent to the houses, the planting surface is adjacent to the courtyard wall and is lower than the hardened ground around the planting surface, and the bottom of the courtyard wall adjacent to the planting surface is provided with drainage holes used for draining rainwater in the resident courtyard into the drainage ditches. The bottoms of the drainage ditches have above one in a thousand gradients, the most tail ends of the drainage ditches are connected with rainwater holes, and the lower parts of the rainwater holes are connected with the pool through pipelines. The system is a comprehensive utilization system of collecting, permeating, retaining and storing the rainwater, and has the advantages of simple structure, easiness in operation, less investment and easiness in implementation, and capabilities of reducing loss of the rainwater due to the hardening of the ground in the villages and towns, increasing water in the soil of the courtyard, forming an ecological landscape water body and improving water environment of the villages and towns.
Description
technical field [0001] The invention relates to a rainwater utilization system and method suitable for villages and towns. Background technique [0002] In rural areas with severe water shortages, our country has already carried out rainwater utilization projects to collect rainwater for drinking and irrigating farmland, such as mother water cellars. This rainwater utilization method is firstly for the needs of survival, and cannot meet the wider utilization of rainwater. [0003] In the construction of a new socialist countryside that has been widely carried out in recent years, drinking water has been provided by cleaner water sources, and drinking water is no longer the focus of rainwater utilization. Cement roads, asphalt roads, concrete floors and roofs in courtyards in the new countryside have replaced the previous soil pavement and ground. This ground hardening causes rainwater loss on the one hand, and increases non-point source pollution on the other hand. The ut...
